Modem Performance
The Modem Performance displays performance information. The primary purpose
is to display the instantaneous throughput rate for both transmit and receive paths
of the modem. This rate is calculated based on the poll period (generally 2 seconds)
and the number of bytes passed during that time.
Transmit and Receive
The throughput is indicated through two bar graphs, each provides a maximum rate
label indicating the transmit and receive bit rates currently in use. The bar graph
displays peak throughput rates over the last 10-second period. Basically, the user
interface records the instantaneous throughput for each poll period over the last 10
seconds, and the peak rate is displayed as the maximum value achieved over that
10-second period. This value is indicated on the throughput graph with a vertical
red marker indicating the peak rate.
The user interface displays operational information about the ADSL modem, rele-
vant when the modem is connected. When the modem is not connected, all of the
non-averaged operational information are reported as zero unless otherwise CSA
User Screen Connection Status noted. This means that when the modem is dis-
connected, these values should immediately report zero.
Connection Status
The Connection Status field changes to indicate the status of the modem connec-
